U.S. state
Hawaii ( hə-WY-ee; Hawaiian: Hawaiʻi [həˈvɐjʔi, həˈwɐjʔi]) is an island state of the United States, in the Pacific Ocean about 2,000 miles (3,200 km) southwest of the U.S. mainland. One of the two non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainlan...
Kīlauea
Active volcano in Hawaii
Kīlauea (US: KIL-ə-WAY-ə, Hawaiian: [kiːlɐwˈwɛjə]) is an active shield volcano in the Hawaiian Islands. It is located along the southeastern shore of Hawaii Island. The volcano is between 210,000 and 280,000 years old and grew above sea level about 100,000 years ago.

Why It Matters
This volcanic eruption matters because Kilauea is one of the world's most active volcanoes, directly threatening nearby communities with ashfall, respiratory hazards, and potential property damage. The release of glassy fragments (Pele's hair) poses specific risks to aviation, agriculture, and human health due to their sharp, lightweight nature that can travel long distances. The eruption affects Hawaii residents, tourists, local agriculture, and air travel in the region, while also providing scientists crucial data about volcanic behavior and eruption patterns.
Context & Background
- Kilauea has been erupting nearly continuously since 1983, making it one of the longest-running eruptions in recorded history
- The volcano's 2018 eruption was particularly destructive, destroying over 700 homes and displacing thousands of residents
- Kilauea is part of the Hawaiian hotspot volcanic chain and sits on the southeastern side of Hawaii's Big Island
- The volcano has multiple eruption styles including effusive lava flows and explosive eruptions that produce ash and volcanic glass
- Hawaiian Volcano Observatory monitors Kilauea 24/7 using seismic networks, gas sensors, webcams, and satellite data
What Happens Next
Scientists will continue monitoring gas emissions, ground deformation, and seismic activity to predict further eruptive behavior. The Hawaii County Civil Defense will likely issue additional alerts regarding air quality, road closures, and evacuation zones if the eruption intensifies. Tourism officials may adjust visitor access to Hawaii Volcanoes National Park based on volcanic activity levels and safety assessments.
Frequently Asked Questions
The glassy fragments are called Pele's hair - thin strands of volcanic glass formed when molten lava is stretched by wind during eruption. These sharp, lightweight fibers can travel miles from the eruption site and pose respiratory hazards if inhaled.
Current activity appears less dangerous than the 2018 eruption that destroyed neighborhoods, though all volcanic eruptions carry risks. The primary concerns now are ashfall affecting air quality and aviation, rather than immediate lava flow threats to residential areas.
Most tourism continues normally during Kilauea eruptions, though specific areas near the volcano may have restricted access. Visitors should check with Hawaii Volcanoes National Park for closure information and monitor air quality reports, especially if they have respiratory conditions.
The Hawaiian Volcano Observatory uses seismic networks, GPS stations, gas sensors, thermal cameras, and satellite data to monitor Kilauea 24/7. This system provides early warnings of eruptive changes and helps scientists understand volcanic processes in real-time.
Volcanic ash contains fine particles that can irritate eyes, skin, and respiratory systems, particularly affecting people with asthma or other lung conditions. During ashfall events, officials recommend staying indoors, using masks, and avoiding unnecessary outdoor activities.
